Windows 7 (previously codenamed Blackcomb and Vienna) is scheduled to be the next major version of Microsoft Windows, expected to be the successor of Windows Vista. Microsoft has announced that it is “scoping Windows 7 development to a three-year timeframe”, and that “the specific release date will ultimately be determined by meeting the quality bar.” The client versions of Windows 7 will ship in both 32-bit and 64-bit versions, even though the server counterpart (which will succeed Windows Server 2008) will be exclusively 64-bit.
Microsoft is maintaining a policy of silence concerning discussion of plans and aspirations for Windows 7 as they focus on the release and marketing of Windows Vista, stating that Microsoft doesn’t want to promise features and then fail to deliver, though some early details of various core operating system features have emerged. As a result, little is known about the feature set, though public presentations from company officials have disseminated information about some features. Leaked information from people to whom M1 of Windows 7 was shipped also provide some insight into the feature set.

Reports also indicate that a feedback tool included in Windows 7 lists some coming features: the ability to store Internet Explorer settings on a Windows Live account, new versions of Calculator, Paint and WordPad that use Windows Presentation Foundation, and a 10 minute install process. UI changes are expected to appear in later builds of Windows 7, though there is already a bright bootscreen present, somewhat resembling pre-XP versions of Windows.
